To` uil 'whom it may concern:

Be it known that I, JOHN PEARSON, a

citizen of the United States, residing a-t novel construction, arrangement and combivview of the part 29.

nation of parts herein 'shown and described,

and ,more particularly -pointed out in the claims.

In the drawings lwherein like reference characters Aindicate like or corresponding parts'Figiii-e 1 isa sectional view of a portion ot "'a cai with my inventionapplied tliereto..one door closed and one door partly open. Fig. 2 a plan view of a portion of the bottom of the car body showing one door. Fig. 3 is a side elevation of a portion of the car and door operating and controlling mechanism. Fig. 4 a perspective Fig. 5 is aysectioiial view taken substantially on line of Figs. 1 and 7. Fig. (i is a similar sectional view with the several parts in the positions indicated by the dotted lines in Fig. 7. Fig. 7 is an enlarged view and elevation showing the parts on the right hand side of Fig. 1. F ig. 8 is a perspective View of one of the shaft supports and hinge parts, and Fig. 9 is aview and elevation of simple means for operating the shaft members.

Referring to the drawings, a complete car is not shown in all its details, as this forms no part of my invention, it being readily understood that my preferred construction may be used on any form of car to which it may be found applicable. In the construction shown the car is provided with ay plurality of dump doors 5--5, etc., on each side, thereof. hinged longitudinally of the car, at the center thereof and arranged to form the bottom or door of the car when they are closed. Referring particularly1 to .atented Dec. 6, A191.0,- I

Fig. 1, suit-ablerbeams l'-`l an il- 31v31 are preferably provided and arranged -lengthwise at the center and sides of-th-car, forni-3 ing a part of thei'car body, Which are suit/1 ably supported from the trucks (not shown) 1n any preferred manner. 2 may be provided, l`as, may suitable' side Walls 3 and membersf4.v The construction A suitableV floor ofthe car body and thelother several partsf of the ear not formingav 1 art of'my inven tion. may be modified an 'made as desired.-

As shown, in lthis figure thedo'ors 5 are arranged on each side ofthe-center beamsv 1v and pivotally supported bysui'table brackets 8 carried by the beams 1. The brackets are preferably extendedas'shown at. 7 andthe.

doors secured thereto by means of pins'v or their-'equivalent forth'e purpose. Preferably carried by the beams arranged a plurality' of members 14, two bearra'nged to support the 'free edges of the doors when closed.. These members. are

preferably pivotally secured as at .1 5 toA brackets 13 carried by the beams 31 and the side walls 3, and-are extended as shown at- 141 so that they may engage a suitable roll 20 carried on a pin 21 or the equivalent for the purpose which is arranged on the .beams 22 and 23 on the bottom ofthe door (see Fig. 2l. The members 16 are vpivotally arranged at 17 to the extensions 14.1 on the posite end of the flexible member or'chain 24 is secured to what may be termed a drum 12 arranged on a winding shaft- 11, which shaft is supported by means ofthe brackets.l 8.'

As shown, thebrackets 8 '(seeFig. y8) are extended as at 9, a suitable bushing 10 being provided where the Winding shaft is asquare or the like` so that the same may rotate in the bracket. The chain 24 may be secured -to the drum in vany suitable way, an extension or lug 25 being shown for the purpose,

the chain 24 being secured to the extension 25 by meansof an eyebolt 26.

Each of the. members 14 is preferably 75 ing shown for each .door which members are provided with an opening 27 therethrough, through which passes 'a slidable rod or `bar 28 arranged along the outside of the oar, which bar carries what 'may be ternied a cam member 29provided with a cam face 30. l As shown,fthe member 29 is preferablyjmade I' in the form ofay Ushapedmemberggand,

I. 'strengthened ,by ribs '31e-gj A may .be made integral with The, member 29 'fthe equivalent for -the purpose;v It. is of icoursefobvious that the parts 'my be so ar- .jgjvrange'd' thatonly the member 29 slides or 1'5 '.`operates in the opening 27. f Aferred.construction there are a plurality of bars 28 'for example two on each side of the .car- -operated from the 'ends of the car, each l -one controlling .half the members 14 on its respective side.

Any suitable means may be employedV for longitudinally moving the bar 28. As most clearlyi shown in Fig. 3, I provided?4 lever 32 provided with an extended ,end33,-which lever is pivotally secured to the carV bodyat.

34 and connected at the extension 33 to the bar 28 by means of a connecting member 35. A guide 36 maybe provided and if desired a loc-k 37 arranged von the bar, thesame-cooperating with notches in the guide `36 so that' the bar 28 may be positively locked in the desired position. 1

Any suitable means may be. enployed to operate the shaft- 11. Referring to Fig. 9,

in which a simple arrangement is shown, 39

represents a lever pivotally ,secured to the car body at 40 carrying a pawl 41 pivotally secured/to thearm at 42, coperating with 12 so that the member 14 is substantially'ln the position shown with the roll 20 resting upon the hooked end 141 so that the weight of the door is carried by themember 14. The member 14 is prevented from swinging outward and releasing the door by means of the chain 24,-the bar 28 and member v29.

'Should the chain be slackenedthe memberv 29 will prevent the swinging out o-me'mber 14 and opening of the door. Assuming that it is desired to openthe door the lever 432 is pushed down in the dotted position indicated in Fig. 3 so that the rod or bar 28 and memberl29 are thrown into the position shown in Fig. 6. The chain l24`may @f5-'ifdelo-en'edfbut 's preerably 'made-separate and;l secured'thereto by means'of bolts, rivets,-jor' '1n the pre-A ,coperating under a strain, that is, wound on the drum ysupporting be now unwound or slackened, whereupon the weight of the dooriyill lcause, the member 14 to swingfout assi'ndicated in the left hand side of'- igJ-l, .spthat the door will vsavv'finlgrd'ownas thel shaftf-illis rotated, the Welg ofthe door being 'supportedby the cham, the member 14 and the connecting vmeans therebetween. TTG close the door the" shaft'll is rotated-'t0 wind the chain 24 on the druml 12 raising the door to its closed osition and Idrawing the supporting memer 1,4 so that the 4roll 20 reststhereupon.

The lever 32 may be then loperated to drawl the bar, 28'and the member 29 back to the position `-indicated in Fig'. 5, thereby positively locking the doors shut, Should any of the members 14 benot drawninto operative position owing to the lengthening of the chain secured thereto or for any other reason, the cam member 29 will force the same into its operative position.

It is thus seen that-in the construction` shown there is substantially no weight of the door on the chains or winding shaft when th'e door is closed, but that the free edges of the door are supported directly from the car body by the members 14, 'which are positively locked into operative position by ther bars 28 and members 29.' vIt 1s of -course obvious that there may be any number of .doors 5, and that they may be arranged in any preferred way.

Having thus descrlbed my invention it is Vobvious that various immaterial modifications may be made; in the construction and combination of'parts herein shown and described without departing fromthe spirit of my invention or that the same may be used wherever found applicable, hence I do not' Wish to be understood as limiting myself to the exact construction shown-and described.
